Notes : 3. This delay is mandatory to avoid a wrong detection of polarity change in the case of a composite syn c.

4. See Figure 10 for explanation of reference phase.

5. These parameters are not tested on each unit. They are measured during our internal qualification.

6. This PLL capture range may be obtained only if f0 is captured (for instance bu adjusting R0). If not, more margin must be provided

between fH (Min.) and f0, to cope with the components spread.
